SCAVENGER ROLL FOR SPlNNlNG-MACHINES, 80C.

SPECIFICATION forming part of Letters Patent No. 375,881, dated January 3, 1888.

Application filed August 17, 1887. Serial No. 247,211. (No model.)

To all whom it may concern.-

Be it known that 1, PERLEY LARLIN, a citizen of the United States, residing at \Varren, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvernentsin Scavenger-Rolls for Spinning and Roving Machines, of which the following, together with the accompanying draw ings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

This invention relates to that class ofdevices which are employed in spinning and roving machines for preventing brokendown ends and waste from winding onto and interfering with the proper working of the drawing-rolls, which devices are commonly known as clearers, wipers, or scayenger-rolls.

Previous to my invention scavenger-rolls made of wood and used plain or covered with cloth, and others provided with a cord disposed spirally about the roll, have been employed on spinning-machines, mounted in relation to the frame and drawing-rolls in substantially the same position and manner as herein indicated; hence I do not claim novelty in the employment or disposition of such rolls in connection with roving drawingrolls for the purpose named. Such rolls as heretofore constructed have, so far as I am aware, failed to fully meet the requirements of the service, since they do not in all instances prevent broken strands of roving from winding onto the bottom drawing-roll, and thus interfere with the proper running of the adjacent top rolls and consequent production of imperfect yarn.

The object of my present invention is to provide a wiper or scavenger roll that will be more efficient, sure, and reliable in its operaformed ofcork, or an equivalent substance that presents a granular surface substantially such as produced by a coating of comminuted or ground cork.

The particular subject matter claimed is hereinafter definitely specified.

In the drawings, Figure 1 is a front view of drawing-rolls as employed in a cotton-spin ning machine, showing my improved scavengerroll applied thereto. Fig. 2 is a sectional diagram showing the relation of the scavenger-roll to the drawing-rolls. Fig. 3 is a side view of my improved scavenger-roll, and Fig. 4 is a transverse section of the same.

My improved scavenger-roll A is preferably made as follows: A body or cylinder of the re quired size and length, formed of wood, metal, or other suitable material, is prepared and provided with suitable journals, 1), for its support. A quantity of cork, sawdust, or cork comminuted or ground to the desired degree of granular fineness is then prepared and spread on a suitable table or flat surface. The exterior of the roll A is then dressed over with a coating of glue or cement and rolled over the bed of comminuted cork, the particles of which adhere to the cement or glue and form-a close granular surface or coating, 0, about the roll, which when the glue or cement has hardened is firmly secured to the body A, and can be dressed off to any degree of fineness or left in its original condition for use, as desired.

' lVhen applied to use, this scavenger-roll is disposed and supported in relation to the drawing-rolls D and F substantially in the ordinary manner.

The granulated cork gives to the roll a semielastic, slightly rough, soft, or spongy surface, by which the fiber is readily taken up, so that the fiber will in all cases adhere to the surface of the scavenger in preference to its adherence to the surface of the metal roll I), while such granulated surface freely and completely yields up the fiber when the waste is picked off, thus leaving the surface clean and in condition for service.

As modifications of my invention, in some instances the roll A can be made wholly of cork, or as a cylinder of cork on a central shaft, the exterior thereof being ground or roughened to produce a working-surface of the peculiar granulated nature desired; or, again, a comminuted substance of other material than cork, but of similar nature, or rubber granulated, might be used to form a granulated coating or surfacing for the roll, and such constructions, whereby a roll is produced having the sen1i-elastic granulated surface, such as described, for taking on and winding up the loose ends of roving and waste fiber, I desire to include within the scope of my invention.

The advantagesiucident to my invention are, that a'scavengenroll havinga granulated surface of the nature described catchesand Winds up the Waste and broken-down ends more surely and efficiently than do the ordinary rolls in use, while the surface is less subject to deterioration by continued use.

Another important advantage is, that Waste can be readily picked off from the roll without liability of tearing off or injuring the covering or surface, as frequently occurs with rolls covered with fabric or cord.

What I claim as of my invention, and desire to secure by Letters Patent, is-

1. A scavenger-roll for spinning or roving machines, composed of or having its exterior surface formed of cork, substantially as and for the purpose set forth.

2. A clearer or scavenger roll for spinning or roving machines, having a rough granulated surface, substantially such as described, for the purpose set forth.

3. A clearer or scavenger roll for spinning or roving machines, having a granulated exterior surface coating ofasemi-elastic substance, substantially as and for the purpose set forth.

4. A scavenger-roll for spinning or roving machines,consisting of a cylindrical body having its exterior surface coated with a comminuted substance of granulated semi-elastic nature, substantially as set forth.

5. Ascavenger-roll for spinning and roving machines, having its exterior surface covered with granulated cork secured thereon by glue his PERLEY LAFLlN.- mark.
